The discovery that transformation was mediated by DNA was made by Oswald Avery, Colin MacLeod, and Maclyn McCarty in 1944 with their experiments on pneumococcus bacteria. They showed that DNA was the substance responsible for genetic transformation, contradicting the previously held belief that proteins were the carriers of genetic information.
No, Frederick Griffith did not discover bacterial transformation. It was Oswald Avery, Colin MacLeod, and Maclyn McCarty who demonstrated that DNA is the genetic material responsible for transformation in bacteria in their famous experiment in 1944.

The structure of DNA was discovered by Watson and Crick
Conjugation Transformation Transduction (A bacterial cell takes up DNA from its environment One bacterium transfers DNA to another bacterium to which it's physically connected A virus moves DNA from one bacterial cell to another)
if transformation is successful , the recombinant DNA is integrated into one of the chromosomes of the cell. The cell will be fundamentally changed, hence the name "transformation".
No, Frederick Griffith did not discover bacterial transformation. It was Oswald Avery, Colin MacLeod, and Maclyn McCarty who demonstrated that DNA is the genetic material responsible for transformation in bacteria in their famous experiment in 1944.
He determined that the DNA is most likely the genetic material and discovered pneumoccal transformation.

== == transformation ------------------------------------------------------------------------------------------------------- Transformation is the process in which a bacteria takes in DNA from the environment. Reference: http://en.wikipedia.org/wiki/Transformation_(genetics) By the way, transduction is the process of DNA transfer by the action of a virus (bacteriophages). The other method of DNA exchange between bacteria is called conjugation, which is the transfer of DNA between bacteria by physical contact.

The process is called transformation. In transformation, bacteria take up free DNA from their environment. The DNA can be integrated into the bacterial cell's genome and can lead to genetic diversity within the bacterial population.
